Panic disorder is a type of anxiety disorder that is characterized by fear and worry. One of the most salient symptoms is the experience of persistent and often unanticipated panic attacks. Panic attacks are typically experienced through a combination of frightening physical sensations and distressing thoughts and emotions. These attacks bring on severe apprehension and discomfort, despite a lack of actual threat or danger.
Anxiety can be either a short-term "state" or a long-term "trait". Whereas trait anxiety represents worrying about future events, anxiety disorders are a group of mental disorders characterized by feelings of anxiety and fear. Anxiety disorders are partly genetic but may also be due to drug use, including alcohol, caffeine, and benzodiazepines (which are often prescribed to treat anxiety), as well as withdrawal from drugs of abuse. They often occur with other mental disorders, particularly bipolar disorder, eating disorders, major depressive disorder, or certain personality disorders. Common treatment options include lifestyle changes, medication, and therapy. Metacognitive therapy seeks to diminish anxiety through reducing worry, which is seen[by whom?] as a consequence of metacognitive beliefs.
“Anxiety attack” is not a formal, clinical term, but one that is used by many people to describe all sorts of things, from feeling worried about an upcoming event to intense feelings of terror or fear that would meet the diagnostic criteria for a panic attack. In order to understand what someone means by “anxiety attack,” it is necessary to consider the context in which the symptoms occur.
